An amazing in game command called /muteall

So I used to be a toxic asshole in my games. I was bronze 4 and thought it was my teams fault. I was always saying shit back to people in chat. Then I started watching Tobias Fate and he demonstrated the /muteall command. Not being able to hear what my teamates or opponents say in chat has helped me reform. I went from a 14 day ban and honor 0 to honor 5 and am now Gold 5. :D mute all everyone. It works like a charm
